U probably plan but are not showing - fire rated Sheetrock and door for the utility room. And I suggest thicker (2x6) exterior walls with proper insulation. I updated our basement last year with hot water radiant flooring - it is fantastic. But mine took 4” insulation below the ~2” radiant flooring… here in Boston

Thanks! I didn't think about a different type of sheetrock for the utility room. The utility room is one big "L" in that corner. You can access the room from the one door that's already there...I've debated adding another one, but it's still accessible, still has adequate clearance, and still has enough room to get equipment in and out should any of that equipment need to be replaced. I guess I could go either way but it seemed like an extra cost for very minor added convenience, and then dealing with furnace noise by the TV. I'll give it more thought.

The walls I'm stuck with unfortunately. The original framing is still up which is 2x4 right up against the wall. It's not ideal, but I can still insulate with rigid foam and can save a decent amount of money and time not having to redo all that work.

If you wanted, you could probably add some furring strips to the framing in order to push the wall out and have more room to insulate.

Thanks! I didn't think about that. I was planning on insulating with 2" rigid foam between the studs then sealing with spray foam. It's not perfect but the city approved doing it that way and it saves a lot of money. Ideally I would have done 1" rigid foam against the wall > studs + fiberglass but here we are.
